Price for Environmental Neutrino-Superluminality
Gia Dvali, Alexander Vikman
We ask whether the recent OPERA results on neutrino superluminality could be an environmental effect characteristic of the local neighborhood of our planet, without the need of vio…
G-Bounce
Damien A. Easson, Ignacy Sawicki, Alexander Vikman
We present a wide class of models which realise a bounce in a spatially flat Friedmann universe in standard General Relativity. The key ingredient of the theories we consider is a…
Non-Stationary Dark Energy Around a Black Hole
Ratindranath Akhoury, David Garfinkle, Ryo Saotome +1
Numerical simulations of the accretion of test scalar fields with non-standard kinetic terms (of the k-essence type) onto a Schwarzschild black hole are performed. We find a full d…
The Imperfect Fluid behind Kinetic Gravity Braiding
Oriol Pujolas, Ignacy Sawicki, Alexander Vikman
We present a standard hydrodynamical description for non-canonical scalar field theories with kinetic gravity braiding. In particular, this picture applies to the simplest galileon…
